The last two years we have struggled to grow bell peppers. The reason was that we had unseasonably cool and wet springs and summers. Many people use hoops or row covers but I stumbled on a secret by accident. I had a bunch of pepper transplants and had no room to put them in the garden so I stuck them in my flower bed . It just happened to be along the concrete sidewalk. They loved it and did better than they ever did in my garden. Because the concrete absorbed the heat and kept them really hot. So now every year I plant them along the concrete side walks and around my rock gardens to absorb that heat from the stones and concrete. Works like a charm. If you don't have a concrete sidewalk try laying big rocks around the base of them to keep them warm.
And peppers aren't the only thing I tuck in my flower beds. I had extra broccoli transplants and tucked them away with the flowers. They haven't had a cabbage worm on them yet.
I think they can't find them : )
